CVD Diamond Wire Drawing Dies the bundle and strand moulds are used to guide and / or organize the wire through the bunching machine and stranding machine,the winding drum of the double and single twist bunching machine is inside the machine,and the mold is fixed at the entrance of the machine to collect the wire. In some cases,the die is fixed to the front of the winding drum inside the machine to regulate the wire,and the strand mold of the tubular and basket strander is inside the machine to guide and concentrate the wire. Process and technology: Targeted pretreatment process:to make the coating and the substrate closely combined Micro diamond coating:excellent wear resistance Surface nano diamond coating:excellent surface finish and low friction coefficient Optimization of pass design by computer simulation

α(ss)Entrance	The inlet area is polished so that the drawing fluid can circulate smoothly
α(sp)Approach	The lubrication area is finely polished, so that the wire can be easily excessive
α(rs)Reduction	The working area can reduce the drawing force, and the change-point contact is face-to-face angle drawing, which reduces friction and die wear. The deformed structure is more reasonable and stable. The upper line can be drawn smoothly when the incoming line becomes thicker or thinner.
d(k)Bearing	The fixed warp area can ensure the precise diameter, smoothness and out-of-roundness of the wire for a long time.
α(so)Back Relief	The safety angle can ensure that the wire is drawn without scratches, and the life expectancy tends to be longer.
α(sw)Exit	The deepening of the outlet can greatly support the tensile stress of the outlet.
The best material depends on the wire you draw and the quantity you draw. Contact us to help you choose the most economical solution and reduce the total cost of ownership of your drawing dies. In the center of the drawing die, there is a hole of a certain shape, such as round, square, octagonal or other special shapes. When the metal is pulled through the die hole, the size becomes smaller and even the shape changes. Wire drawing is done by passing the metal wire through the hole of the wire drawing die, and applying a pulling force to the wire at the exit side of the die. The wire is contracted and squeezed in the mold cavity and gradually becomes thinner, and its speed increases near the exit of the die hole. Because the volume of the wire is constant, the reduction of the cross section makes it stretched.

CVD (Chemical Vapor Deposition) coated wire drawing die is a new technology that has been developed recently, and its main method is to coat diamond film on the hard alloy wire drawing die.
The diamond film is pure diamond polycrystalline. It not only has the smoothness and temperature resistance of single crystal diamond, but also has the advantages of polycrystalline diamond wear resistance and low price. It has achieved good results in replacing rare natural diamonds in the preparation of wire drawing die tools. Its wide use will bring new vitality to the wire drawing die industry.

According to the types of materials, the wire drawing dies can be divided into alloy steel dies, cemented carbide dies, natural diamond dies, polycrystalline diamond dies, CVD diamond dies and ceramic dies.
